IMPRVEMENTJN DROP-LIGHTS AND HANGERS.

Specification forming part of Letters Patent No. 144,309, dated November 4, 1873; application led September 5, 1873.

` To all whom it may concern.'

to be a full, clear, and exact description of theI invention, such as will enable others skilled in the art to which it pertains to make and use it, reference being had to the accompanying drawings, which form part of this specification, in iwhich-- Figure l is a front elevation, showing the casing.` Figs. 2 and 3 are elevations of the gasalier with the casing removed. Fig. 4 is a plan of the headlor upper body.

The object of our invention is to produce a sliding chandelier in which the harp or droplight may be readily and easily lowered and kept in any desired position without the employment of springs or binding devices. A further obj ect of our invention is to provide an arrangement of the main pipe and sliding pipe whereby each of said pipes shall be wholly independent of the other, instead of the latters sliding within the former, as heretofore.

Referring to the accompanying drawing, A shows the stift' joint proceeding from the ceiling, to which is secured a head, B, having the ways b and b1 for supplying gas tothe main pipe and sliding pipe, respectively. O is the Inain pipe, which is screwed into the head B and body D, the latter being supplied with suitable ways for communicating with the branches. E is the sliding pipe, which moves vertically through an opening in the body D, and upon its supplypipe E, which is screwed into the head B. F is a weight, arranged to counterbalance the sliding pipe and harp, being connected, by means of the pulleys b2 b2 and f j' and the cords j" ff, with said pipe, so that on pushing up the drop-light the weight will descend, and vice versa, retaining said light at any altitude desired. G represents the covering-tube, which surrounds and completely conceals from view the several parts above described, permitting the indispensable ornamentation ofthe chandelier to be effected.

B y the above-described construction, the use of springs or binding devices is wholly dispensed with, and a cheap, simple, and effective arrangement provided by which the drop-light may be easily drawn up and down with one hand. Economy in construction is also obtained, as by this arrangement of the pipes the main pipe may be made of iron, it having lbeen found necessary heretofore, when the sliding pipe was located within it, to make said main pipe of brass in order to obtain the required thinness of metal, so as to preserve the proper proportions of parts and make the casingpipe of not too great diameter. While the complete separation of the main and sliding pipes is thus achieved, and the obstacles to the employment of a weight-which is per se the simplest and best retainer for the droplight-overcome, the entire operating devices are completely hid from View, being all contained within the coverin g-tube, which is thus made susceptible of that ornamentation in the direction of massiveness which the popular taste demands. y

Were the `sliding pipe outside the coveringtube, it would require to be duplicated in order to preserve symmetry, thus increasing the eX- pense, and giving anobjectionable skeletonlike appearance to the chandelier, the main stem and body of which would also necessarily be diminished in its lateral proportions or rotundity.

What we claim as our invention is l. The combination of the supply-pipe E', main pipe O, and sliding pipe E, said main and sliding pipes being apart from each other and not concentric, and located within the covering-tube G, as specified.

2. The covering-tube G, located above the body D of an eXtension-gasalier, and inclosing the counterbalancing-weight, said weight being connected to the sliding pipe by cords and pulleys, and moving vertically within the coniines of said covering-tube, substantially as and for the purpose set forth.

3. The combination of the main pipe O and sliding pipe E, said pipes being apart from each other and non-concentric, with the counterbalancing -weight F connected with said sliding pipe by 'cords and pulleys, as shown, all of said parts being located within the coveringtube G, as specified.

In testimony that we claim the foregoing we have hereunto set our hands this 29th day of i August, 1878.
